Roof tiles – a general overview
Constructing in an economical manner is an important condition for architects and building owners, but it is often ignored that those building materials are economical which lasts longer – and not always the ones, which costs less. Costs for repairs and maintenance may quickly exceed the amount saved when buying the component. Those calculating costs over the long term, will decide for quality and lasting operative readiness. This is particularly true for the tiled roof as compared to other cladding materials such as slate or metal.
A modern roof material
Modern roof materials such as clay roof tiles are used for single-family homes and apartment buildings, office and industrial complexes as well as refurbishment projects. The production process is based on the four elements of earth, water, air, and fire. The natural components promote a healthy living climate, provide reliable protection for residents and are additionally recyclable.
The blanks are produced from a clay mixture, shaped as desired in a moulding process, dried and subsequently fired – that’s how a pure and natural ceramic product is manufactured. At Wienerberger, a computer-controlled production process and continuous quality control ensure that only top quality products are supplied.
The colour of clay roof tiles is determined by the natural composition of clay. For natural red tiles, ferrous oxide contained in clay is responsible for the slightly iridescent colouration. If oxygen is deprived during the firing process, the unglazed ceramic material turns bluish.
Another, almost unlimited colour spectrum is achieved when applying and firing clay slurries and their mineral composition. They are firmly burned in the roof tile and do not fade.
Each one of the different shapes with its typical, characteristic features has developed from regional conditions. The following main groups can be classified for roof tiles:
Tiles with interlocking
- Flat tiles
- Profiled tiles (Pan tiles, Tempest tiles, Reform tiles, Mulden tiles)
Tiles without intelocking
- Plain tiles
- Overlapping tiles (Hollow tiles)
- Over and under tiles (Monk&Nun tiles)
Besides roof tiles for the roof area there are special ceramic accessories for the cladding of ridge, eaves, verges and hip. Special accessory tiles such as ventilation tiles, antenna passage tiles, vent pipe systems etc. additionally ensure the functionality und permanence of the entire roof.
